Tonight's Snow Situation

We saw plenty of snow showers leading to some accumulation all across Western Washington, but most of it melted through the day. Tonight we face the threat for accumulating snow through the I-5 and I-405 corridors as a deformation band sets up. As seen on radar, band of snow will form in the south and track north across the Puget Sound. Since it is night and temps are close to freezing, it will not be too difficult for snow to stick, including main roads. A lot of uncertanity exists as to where these bands set up and how intense they will be so you can pretty much throw out all the models for the next 12 hours as this will be a watch the radar sort of event. 

WWA's are out for the central Sound for up to two inches of snow, this is a good move from the NWS considering the amount of uncertainty. I will also go for 1-3 inches for most of the central Sound, however areas where the bands train over could see more than that.  

This is a tricky forecast and I may do another update in an hour or so based on how the radar looks.

Good luck!!

Widespread Lowland Snow Incoming!!

 Well it is going to be an interesting 48 hours coming up. We will have snow, ice, sleet, rain, wind, basically everything on the weather bingo card in the next 2 days.  A strong and moist Pacific system will move into the area tomorrow evening, spreading precipitation into a very cold and dry air mass. A ripe set up for a snowstorm in the PNW.  Current satellite imagery shows moisture moving into Oregon.  This moisture will spread north and with the cold temperatures in place, it will bring wintry weather to the lowlands of Oregon and Washington. Winter and ice storm warnings are out for Portland and the Willamete valley. This storm will work effectively to scour out cold air in the upper levels so I expect precipitation type to quickly transition to freezing rain and sleet south of Salem. However, upper levels should stay just cold enough for precipitation to remain snow north of Wilsonville.  The low will pull east winds out of the gorge, keeping things very ...

Friday Night Update

The much talked about potential for lowland snow is finally here and we are in the range where we can talk about specifics. Tonight, a cold front is crossing the area, evident in satellite imagery.  Behind this cold front is much colder air which will filter into the area tonight. Temps are sitting in the upper 40's currently in much of the Puget Sound, by about 2 AM, much of the area will be in the 30's and a gradual cool down will continue. At this time there are several chances for lowland snow, but accumulations will be spotty as the system is more showery in nature and not organized.  There will be several areas with a heightened potential for lowland snow and I will point it out on this little graphic.  Zone 1 is in Snohomish county and has a heightened potential for snow due to the convergence zone setting up over there tonight and into tomorrow. There is a chance this extends southwards briefly so some of northern King county could also see some snow. I expect abo...

Evening Update

 We are very close to tonight's snow potential and models still have no idea what will happen. Looking at Sattelite imagery, the low pressure we have been tracking looks to be a bit north of Hoquiam. How north this low goes will determine which area gets the most moisture. Earlier this area looked to be King County and the Central Sound, but now this area may have shifted a bit northwest. Northern King County and the Kitsap peninsula.  As I said earlier, this looks to be a bit more widespread in terms of moisture, but temps look to be more marginal so elevation will definitely aid with snow. Looking at the graphic below, the area circled in blue will have the most access to moisture tonight. In this area, places above 500 feet should see 2-8 inches of snow. Below that, 1-3 inches of snow seems likely. Another wildcard going into tonight is the deformation band as the low passes to the south of us, the models are struggling to nail that feature but if it does form then areas un...
